Abstract
A method for the control of an actuator of a starting clutch of a motor vehicle. The actuator is so regulated by a control apparatus that the starting clutch is closed upon the presence of a desire for starting, as well as closed by an adjusted, transmission ratio, and the clutch is opened upon the termination of the starting procedure. For the freeing of a vehicle from a roadway obstruction by way of a rocking process of the vehicle, it is proposed that the starting clutch, during a starting procedure and by way of control of the actuation actuator, is operated in a fully automatic manner in such a way, that the torque (M_K) periodically varies.
